JQuery :: Upload Files Form Plugin - Breaks Xhr Detection On Server
Sep 16, 2010
From the little I've read in this plugin's source code, ajaxSubmit() switches to "iframe mode" whenever it detects a file link in the form. The file is uploaded fine, but the server, which normally replies with different content. based on HTTP_X_REQUESTED_WITH header, fails to do its thing. This header is normally set to "XMLHttpRequest" on normal jQuery .ajax() calls.
The server I'm running is on rails, and I'm using the "request.xhr?" test.
I admit I'm not too familiar with iframes (or jQuery, for that matter:), but surely there must be a way to get around this, so that this can act as a simple drop-in replacement. Should I be looking at other headers, like "Accepts" or the kind, or should the plugin (or my code) be forcing the HTTP_X_REQUESTED_WITH header?
I have an upload form that is working fine with a submit button, but I really would like it to submit on its own without a submit button onChange when a user selects an image. I have it sending the form with onChange but it is not sending the uploaded file like when you hit the button! It is sending it as "example.jpg" instead of actually sending the file for upload.
I am trying to implement this jQuery form plugin to do ajax file uploads. Although the documentation is great I am still a little unclear about one thing. Usually when I do ajax submissions I return a response in JSON(using PHP), something like :
When doing some simple tests I have run into a problem and I believe it is due to the way this plugin handles JSON responses. My form :
[Code]...
This does not result in the success event firing but rather the error event. In the plugin documentation it states that it does not handle json responses well and that it recommends wrapping the response in a textarea. Unfortunatly I'm not sure what they mean by that, and what I've tried so far has not worked. ould anyone give me some advice as to how to output the response in JSON properly? Could anyone that has used this plugin for AJAX file uploads offer any advice on doing so?
I've added file upload support to the form plugin and I could use some help testing it out.If this feature interests you then go ahead and grab the beta plugin at:URL...File upload support is baked right into the plugin and there are no external dependencies.The plugin will automatically detect file input elements and use an iframe to submit the form if there are files to be uploaded.No extra coding or metadata is needed to take advantage of this new feature.In addition, even though an iframe is used instead of the XHR object, callbacks and global triggers still work as expected (so any code that you have in place to display activity indicators or blocking elements will still work).However, there are some challenges when using iframes in this manner.For one, it is quite difficult to determine if the submit operation succeeded or failed.The iframe becomes the target of the submit operation and so that is where the server response is written.The form plugin does its best to determine the data type (html, xml, etc),but the status is always 'success' unless an exception is caught during the type determination.URL...
If you use this page for testing *please* be kind to my server and only upload small files! I'd really prefer that you download the plugin and integrate it into your own test environment if possible.I've done some testing on FF, IE and Opera and the results are encouraging. I don't have access to Safari so I'm sure there are issues lurking for that platform.If you're interested in the code you can find it all tucked into the end of the ajaxSubmit method in a function called "fileUpload".
I found this formwizard script example online but I don't know how to use the data with php for emailing and saving to database for example.The script attaches the result to <p id="data"></p> like this
how can i call a web method asynchronously to upload a file in database ? In my web page i have to implement multiple attachments and all attachments should to uploaded asynchronously to database on click of a Button. Note that clicking button should not post the form to server, rather that should only upload the files How can i achieve this ?
This is driving me nuts. I'm using the File Upload. It works fine in Chrome, but in FF4 and IE9 it executes the beforeSubmit, but never reaches the success, and the file never reaches the server.
I have a problem with the latest version of the jQuery Form Plugin (2.80). To be more precise, I guess I am doing something wrong, and with an older version (2.67) somehow it didn't matter.With the old version, the file was uploaded without problems. Now Firefox opens a new Tab on clicking the submit button and nothing is done. Chrome doesn't open a new tab, but also nothing happens. In Wireshark I can see that there is no file attached in the POST message with the older version, the file was sent.My first guess was that my file handling on the server side is erroneous - but on the other hand, when there is no file attached, what should I handle there?
I'm novice with jQuery and Web in General and I have a problem with "jQuery Form Plugin" [URL]... Everything works well except when trying to upload large files (I need to upload video files).Itriedupload a video with about 24 MB in the example(demo) page in the[URL]../#file-upload and seems that i don't get the expected result. Can you tell me what constraints or custom options i'm facing with this plugin or IIS7 for that matter? Is there a way to see that something went wrong? Because the file seems to be uploaded but nothing happens after.
I'm working with a Drupal site and am trying to stay within the results of a Drupal view.I'm using Cycle to rotate through a bunch of images created by this view, and I want to use an ajax "page refresh" to check for new content. I get the new content just fine, but then cycle breaks. Here is my function:
function ajaxRefresh(){ $.post('my_site', function(data){
Simple enough. This beautiful plugin is what I"m using:[URL]..The problem is, it has no documentation on how to detect a post failure. I know these are rare, but I'd like to code defensively.
I am using the Cycle plugin in several slide implementations on my website here:

I have recently upgraded the Safari browser on my desktop (Apple Mac Mini running OS X 10.5.8) to Safari 5.0.6 and noticed that the Cycle plugin completely breaks in this version of the browser. My laptop, a Powerbook running OS X 10.4.11, has Safari 4.1.3 installed and the Cycle plugin works absolutely perfect in this version.
I have upgraded the linked JQuery library to version 1.7 as hosted on the JQuery web server [URL] and have even gone as far as downloading the Cycle Lite .js file and hosting it on my own server. None of this solves the plugin breaking in Safari 5.0.6; seeing as I have no issues using the plugin in Safari 4.1.3, I am assuming that this is an issue with the Cycle code as it is being called in Safari 5.0.6
Does anybody knows a good jQuery multiple file uploader? The idea is when somebody click on the Upload link some kind of popup box needs to appear. Something like the media uploader in WordPress. The background of the website becomes grey, and only a upload box appear. It would be cool that only if you have selected one file, the next input for a new upload appear with a max of 9 uploads at a time ...
Anyone have a link or search term for a way to allow the user to upload a list of file names to a web form? I do not need the actual files, just the file names -- name only or full path, doesn't matter. I can live with either just pointing to a directory and grabbing every file name in it, or requiring the user to select all the desired files from within a directory list. (My guess is that the JavaScript sandbox for a web form won't allow this, but I figured I'd check with you experts before looking into other possibilities, e.g. Java applet, etc.) I'm already using the JQuery library for some other stuff, in case there's something I should be looking for there or one of its plug-ins.
I have used this script for multiple upload using one file control. In this i have give limit for upto 3 times user can upload. also user can remove which is uploaded. But main problem is when user remove last uploaded file than its ok but when user remove first uploaded file and then add new file that time user can upload more than 3 files? Whats the problem I can`t found.
My script is
<script language="jscript" type="text/javascript"> function getCount() { var cnt = 0; for ( var i = 0; i < upload_number; i++ ) {
Adding a new plugin page only has Project resources section which only has links to refer.Is there any way by which I can just attach/upload my plugin source code instead of linking to some website?
I have to create a web page to give to clients that is shipped on CD. The idea is that they would open the page and it would display in their web browser.
What this will do is to provide a list of most recent changes to the software we're shipping. The idea is that there would be an un-ordered list <ul/> with a list of changes (not sure of final desired mark-up).
What we want to do is to get the developers to edit a file that simply contains a list of changes, putting in minimal markup. This "changes" file would then be "included" in some way into a parent file that contains all the branding and other information. We don't want the developers to have to navigate their way around this parent file looking for where to edit it.
As this page will be launched in a browser from disk, there won't be any help provided by a web server, so I'm really stumped as to how to accomplish this....could it be done with JavaScript at all?
I am developing extension which should upload currently displayed html as a file to a remote web server, unfortunatelly so far i haven't suceeded. I think this should be done through XMLHttpRequest(), but neither I know how to upload files through XMLHttpRequest nor how to convert string to file.
The HTML form that uploads a file:
But as I said i need my plugin to do it automatically and file must be made from html code.
I'm new to this and i'm trying to use the jquery datepicker plugin. What I want to know is which files to download and in what folders should i put them so that i can use it. I've been using date picker by linking to external js files but i'm trying to figure which files to save on my computer.
dt_save is a <form>, the submit trigger works as usual but when doing an Ajax request the code interrupts without any error. I put in 2 alert's just to check, only the first alert box appears when submitting the form. Also I can't find my request in Firebug's Network window (Firefox addon).
